Automated doppler velocimetry using a low-cost transducer

A computer readable medium for an ultrasound body-fluid-flow analysis device, said medium comprising instructions executable by a processor of the ultrasound body-fluid flow analysis device for carrying out a series of acts, said series comprising:

• a) examining, using an ultrasound probe of the ultrasound body-fluid flow analysis device, a volume to find body vessels present within the volume;
• and,
• b) if one or more vessels are found within the volume in said examining, then b1) selecting, for fluid-flow analysis, a vessel from among said vessels found within the volume, b2) generating, for said fluid-flow analysis, information particular to the selected vessel, b3) determining, based on the generated information, whether said selected vessel matches a target vessel, and b4) if the selected vessel matches the target vessel, then b4) (i) providing, based on the generated information, an indication as to normality of fluid flow in the selected vessel, else b4) (ii) repeating the selecting, generating, and determining with a next vessel of the vessels found, until there is no further next vessel of the vessels found within the volume,
• wherein said acts of examining and selecting (i) do not rely on a display of ultrasound scan images, and (ii) are performed automatically and without need for user intervention to interpret an ultrasound scan image.

A method for ultrasound body-fluid-flow analysis, said method comprising:

• configuring an ultrasound device for performing, automatically and without need for user intervention to interpret an ultrasound scan image, a series of acts, said series comprising:
• a) examining, using an ultrasound probe of the ultrasound device, a volume to find body vessels present within the volume;
• and,
• b) if one or more vessels are found within the volume in said examining, then b1) selecting, for fluid-flow analysis, a vessel from among said vessels found within the volume, b2) generating, for said fluid-flow analysis, information particular to the selected vessel, b3) determining, based on the generated information, whether said selected vessel matches a target vessel, and b4) if the selected vessel matches the target vessel, then b4) (i) providing, based on the generated information, an indication as to normality of fluid flow in the selected vessel, else b4) (ii) repeating the selecting, generating, and determining with a next vessel of the vessels found, until there is no further next vessel of the vessels found within the volume,
• wherein said examining and selecting do not rely on a display of ultrasound scan images.
